The Schedine referrer; to in chene Ltferratent and making' pm of the amI JMES'= C. ,MOORE, of Philadelphia, county "of Philadelphia, State. ofFenuyslvania, have invented a'n Improvement in Hydrantsaud Fire-Plugs',of which `thefollouiing is a 'specification.`

{Nd-ture mul Object of the I nrcnto'n. My-iiivention 4consistslin thecombination, as deV p scrihed hereafter, of a perforated `pipe or aperforated @oas-ing, towhich gas cauA headrnitted, with the pipe fofajhydrant, or lire-plug, so that'wheu the water in e the said pipebecomes frozen it cau be rapidly thawed by. being exposed "to auumber ofdames, as described hereafter.` Y 4v,Dc sfzripton of the AccmnpanyingDrawing.

vA number of arnes or jets is thus caused to'play'.

on the pipe A, and as these jets are arranged in a circle round andbelow the top of the pipe, a. constant current-of hot air will be causedto ascend round lthe upper part ofthe pipe, so that the ice in thelatter is" thawed rapidly, after which the gas may be turned oli', andthe plate ireplaced.

'. Although aperforated coil is'to be'preferredin illust cases, it willbe evident that the pipe may be surrounded with an -anuulal perforatedcasinghto which the gas is admitted.
